青海省大柴旦行委绿草山地区水系沉积物测量地球化学特征及找矿方向

Geochemical Characteristics and Ore Prospects of lvcaoshan Area Based on Stream Sediment Survey in Dachaidan, Qinghai Province

摘要:

通过开展绿草山地区1∶5万水系沉积物测量工作，获得了较为丰富的区域地球化学测量成果。对绿草山地区地球化学特征的分析探讨认为，该区元素的富集、贫化与地层、岩浆岩及构造明显相关，Au，Bi，Hg，Pb，Sb等元素变异系数较大，易形成异常；该文重点讨论了3处找矿远景区的地质、地球化学特征，并就远景区内可能的找矿方向做了进一步分析，为该区的找矿勘查提供了思路。

Abstract:

The study of the geochemical characteristics of Lvcaoshan area was based on the 1:50 000 stream sediment survey, and plentiful regional geochemical survey data was obtained. The analysis of geochemical characteristics in Lvcaoshan area explore that the enrichment and depletion of elements relate to the formation, magmatic rock and structure. The coefficient of variation of Au, Bi, Hg, Sb and Pb is larger, which is easy to form abnormal. The geological and geochemical characteristics of 3 prospecting areas are primarily discussed, and the possible prospecting direction in the prospective area is further analyzed, which provides ideas for prospecting in this area.
